To all Iwhom it may concern:

lie it known that 1, WnNonsLAUs F. MrKoLAsnK, av subject of the Emperor of Austriafand residing at Vodnany, in the county oiBonhomme and State of South Dakota, have invented certain new and useful Improvements iny Egg-Testers. of which the following isa specifica ion.

rl `his invention relates to improvements in egg testers of that type in which the egg is held against any suitable source of light supply in order to inspectits translucency, a muddy or -cl'oudy appearance indicating deterioration.

The object oithe invention is to so construct the apparatus as to obviate the necessity o conducting the testing operation in a' dark room, and also to provide means wh'ereby the egg can be readily supported and rotated so as to be ,observed fronrall sides.. For a ull understanding of the invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for effecting the result, reference iste be had tothe following description and accompanying drawings, in which'.

Figure 1 is la perspective view of the improved egg tester, portions being broken away; Fig. 2 is a longitudinal sectional view through the same; and, Fig. 3 is a transverse sectional view on the line :v-x of Fig. 2.

Corresponding and like parts are referred t'o in the following description and indicated in all the views of the drawings by the same reference characters.

The numeral lrdesignates the body or casingof the egg tester which may be of any suitable shape and is shown in the hpresent instance as being cylindrical, lhis easing l is designed to inelose any suitable source of light supply such as indicated at 2. Projecting laterally from one side of the casing 1` is a tube 3 which is preferably slightly 'contracted toward its outer end and 'forms the aperture through which the'egg being tested is viewed. Projecting laterally from the opposite sides of the easing 1l and in alinement' with the above mentioned tubo 3 is a second tube 4, the outer end of which is provided with a reflector 5 by means of which the light passing enable the eggs to be quicklyand thoroughly tested. A pair of spring arms 6 and 7 project outwardly iromopposite sides of the extremity of the tube 3 and carry the 'cup shaped members 8 and 9 between which the egg is neld..`

As shown in the drawings, each of the arms 6 and 7 is formed with au offset portion lfhynneans oi which through the tube 3 is intensified so as to` l 'smaller' end of said tube as and vfor the purpose set forth.

their extremities are thrown apart,l so that their outer 5) ends, which carry the cup 'shaped members 8 and 9 will lie entirely outside of the margin of the contracted ends of the tube 3. The lower cup"8 is provided with a stub shaft 11 which is journaled within a sleeve 12 projecting from the extremity of the 'arm 6. Qlhe upper cup shaped member 9 is carried by a shaft 1S which passes loosely through a sleeve 14 projecting from the arm 7, and is provided at its extremity with a crank 15. 1nterposcd between this upperl vcup 9 andthe arm 7 is a coil spring 16 'which surroundsI the shaft 13 and operates to force the cup into a close engagement with ,the egg. ln order to prevent any injury to the eggs while being tested, each of the cups 8 and 9 is preferablyy lined with some soft material, such as felt.' With this construction, it will be apparent that when the shaft 13 ispulled upwardly, the eggs'can be readily placed in position between the two cups 8 and 9, and the spring 16 will cause the cups togrip the egg when the shaft is released., The egg can then be revolved through the medium O- the crank l5 and viewed from'all sides. The hood 17 l A which shuts off the external light from the egg enables the testing operation tobe conducted in the light and is in the nature of a conical projection at the outer end of the tube 3. Any suitable material such as sheet, metal may be employed in the construction of the hood 17 and the inner face of the hood is preferably blackened so as to counteract to as great an extent as possible the effects of the external light. i Having'thilsdeseribed the invention, what is claimed as new is:

-An 'egg tester, comprising a easing adapted' to contain a sour-ec oi' light, tubes 3 und 4 intersecting said casing coincident with the source of light und extending from opposlte direetlons thereof, one tube being provided at its outer enti" with a refiector, and the two tubes tapering from said re- 85 llector to'wnrds the outer end of the other tube, i conical hood having its smaller end surroundlngl and secured to the smaller end o1 the' tube 3 and projecting outwardly beyond said end, arms G and 7 ,secured to the said end of the cubel 3 within the said hood, the'said arms being offset '90 outwardly and the said olfset portions being located onthjely without the margin of the smaller end offthe tube 3, und nien-ns securedto theoftset portions of said arms, for holding an egg within the hood und in registry with the 95 In testimony whereof I ux my signature in presence oi' two witnesses.`-
